Abstract

An apparatus 12 for determining when to shift a bicycle chain 58 from a first sprocket having a first number of teeth to a second sprocket having a second number of teeth comprises a memory 182 for storing a reference value, and a processor 170 that determines a shift value corresponding to a shift speed for shifting the chain 58 from the first sprocket to the second sprocket by multiplying the reference value by one of the first number of teeth and the second number of teeth and dividing by the other one of the first number of teeth and the second number of teeth.
